The innovation and development of recirculating aquaculture system ( RAS) technology in Europe keeps continuing, with the strengthening of environmental regulations in EU and European countries. This paper introduced and analyzed the development status of European recirculating aquaculture system, such as the application of Life Cycle Assessment (LCA) method for evaluating the environmental impact of RAS, and the increasing species diversity of RAS production, etc. The paper also highlighted the application of denitrifying reaction technology, sludge concentration technology, and ozone treatment technology in RAS. On this basis, the paper pointed out the new challenges with which the recirculating aquaculture system may be faced.%欧洲循环水养殖系统技术随着欧盟和欧洲各国环保法规的加强而不断创新和发展.本文对欧洲正在使用生命周期法对循环水养殖进行环境影响评估的状况,以及欧洲应用独特的循环水养殖系统技术增加了养殖的品种进行了介绍和分析.并着重介绍了欧洲循环水养殖系统新技术的应用及其发展状况,特别阐述了脱硝反应技术、淤泥浓缩技术和臭氧技术等新技术在循环水养殖系统的应用情况.在此基础上,指出了循环水养殖可能面临的新挑战.
